Abstract

The invention relates to an auxiliary device for flange plate welding of a tunnel air and water pipe and a using method of the auxiliary device. The auxiliary device comprises at least two supporting assemblies distributed in the length direction of the air and water pipe; each supporting assembly comprises a connecting piece, two supporting frames and two rotating pieces; each supporting frame comprises a transverse rod, a first supporting rod and a second supporting rod, the first supporting rod and the second supporting rod are fixedly arranged at the two ends of the transverse rod respectively, and the transverse rod, the first supporting rod and the second supporting rod are arranged in a U shape; the connecting pieces are arranged on the first supporting rods and the second supporting rods and are connected with the two first supporting rods and the two second supporting rods. The two rotating pieces are arranged on the corresponding two transverse rods, rotating shafts of the two rotating pieces are parallel to the transverse rods, the air and water pipe is axially parallel to the rotating shafts of the rotating pieces and are placed on the two rotating pieces, and the head supporting assembly and the tail supporting assembly are close to the two ends of the air and water pipe respectively. The operation difficulty can be reduced, the welding quality is improved, the transportation efficiency of the air and water pipe is improved, and the loss rate of energy is reduced.

Description

technical field [0001] The present application relates to the field of welding auxiliary equipment for tunnel engineering, in particular to an auxiliary device for welding flanges of tunnel wind and water pipes and a method for using the same. Background technique [0002] my country has a vast territory and numerous mountains and rivers, so it is often necessary to build tunnels during foundation engineering construction. Pneumatic tools required for normal construction such as rock drills, pneumatic drilling rigs, shotcrete machines, etc., in the tunnel construction process, if these machines are to work normally, sufficient compressed air and pressurized water sources must be supplied to each wind machine. [0003] The compressed air is supplied by an air compressor, which is usually located at the entrance of the cave, and the pressurized water source is provided by a reservoir at the entrance of the cave. The height difference or booster pump is used to ensure the cons...
